Buying Consideration For The Best Loudest Marine Speakers

Do you want to have the loudest marine speaker in your boat? Then there are some crucial factors that you need to consider.

I can understand if you still feel a bit confuse about choosing your marine speaker. To help you get more clarity, I will sum everything up for you.

Below, you can find some determining factors that make a reliable marine speaker.

High-Quality Construction

The marine speaker is different from the regular speaker. For a sound device on the boat, sound quality is not the only thing that matters.

You should also make sure that your speaker can handle the harsh elements of nature.

That’s why it’s essential to install a speaker that’s built with a marine-grade construction. So you need to make sure that your speaker has a waterproof feature.

Otherwise, it will perish by the unforgiving salt air and other severe conditions.

An excellent marine speaker is designed to fight against all kinds of elements in nature. Therefore, it will be able to accompany your watery escapade for many years to come.

Speaker Sensitivity

Speaker sensitivity measures in decibels (dB). It defines how effective your marine speaker can convert power from the amplifier to create energy. The energy will then translate to the audible waves.

The higher decibels your speaker has, the lower power that it needs. The average home theater speaker usually has around 82 dB rating.

When the number goes up to above 86, you can identify the speaker as a high-quality model.

Meanwhile, for a marine speaker, the number should go to no lower than 80 dB. If you can get a speaker with at 90 dB rating or above, it will work highly efficiently in converting power into full and resonant sound waves.

Frequency Response

Frequency response measures in hertz (Hz) and refers to the range of frequency a speaker can produce. As we age, the maximum auditory range we can hear will decrease. But under normal conditions, human hearing is ranging between 20 Hz to 20,000 Hz.

Lower frequencies represent bass sound, while higher frequency will produce treble sound. The bass sound falls in the range of 15 to 30 Hz, while the treble sound is part of the audio above 2,000 Hz.

To be able to represent an excellent sound quality, your speaker should cover the above frequency range.

Almost all marine speaker features a 2-way system. As you can read in the reviews above, a marine speaker usually consists of a woofer and tweeter.

Each of these drivers handles a dedicated range of frequencies. The woofer is the one handling the lower end of the spectrum, while the tweeter works on the higher frequency.

There are also 3-way speakers on the market, and I’ve reviewed one of them earlier. For the 3-way speaker, there’s an additional mid-range driver other than a woofer and a tweeter.

If you expect to get a comprehensive sounding out of your marine speaker, then you better go for a speaker offering a full-range frequency response.

Power Handling

One of the things that make an excellent marine speaker is its ability to handle power. In order to produce a loud and vibrant sound, your speaker should be able to handle at least the same amount of energy that the amplifier can deliver.

It is important to note that impedance and power handling are a critical factor in choosing the loudest marine speaker. Actually, if we talk about marine speaker power, things can get a bit complex.

It is quite technical and can be confusing for some people. But I’ll try to simplify it a bit. So at least you can get an idea of why this is important.

The first thing you need to know is, power measurement can vary from one manufacture to another. Let’s say you’re using a typical stereo head unit, which is rated at 200 watts of peak power.

But your speaker may not necessarily need to handle 200 watts power. In case the head unit has 4 channels, the number will be divided by 4. So what your speaker needs to handle is 50-watt power.

Now let’s go a bit further. You might have noticed from the above reviews that there are 2 kinds of power, the peak watt, and RMS or continuous watt. The RMS value is always lower than the peak power value.

When choosing a marine speaker, you should focus on the peak wattage value than the RMS. The reason being is because RMS represents the continuous power your speaker can handle.

Meanwhile, peak power is the maximum power a speaker can handle before resulting in distortion or failure.

Frequently Asked Questions (FAQs) – About Marine Speakers

01. Are Marine Speakers waterproof?

The marine speaker is different than the regular speaker. It is specifically designed to handle the harsh marine environment. Otherwise, it wouldn’t be able to do the job well and most likely will perish during your first trip to the sea.

However, being waterproof and being water-resistant are two different things. Water-resistant means the speaker can handle water exposure.

The term water-resistant is commonly used to describe a product that can resist water penetration. Meanwhile, a waterproof speaker is impervious to water.

So I would say that all marine speakers all water-resistant. But it may or may not be waterproof.

You need to check the features of each product carefully to figure out which speakers are waterproof and which are merely water-resistant.

Though you wouldn’t dive carrying your speaker, it’s still better to go for a waterproof speaker whenever possible. That is because a waterproof speaker can better endure water pressure.

For example, during heavy rain, a waterproof speaker has a better chance to survive than the water-resistant one.

02. Can marine grade speakers be submerged?

Marine-grade typically has IP certification. It means the unit is waterproof and can handle water pressure and heavy water exposure.

Some manufacturers even claim that you can dunk their product, and nothing bad will happen to the speaker.

However, I’ve never tried it myself or see anyone demonstrate it. But yeah, it’s theoretically possible to do that. Though I don’t think there’s any reason for you to actually do that.

Unlike a phone or iPod that you can take while swimming, the marine speaker is something that you install on the boat.

But if you’re just curious about how well it is in dealing with the water exposure, then you can refer to the above explanation.

03. Can I use marine speakers in my car?

The short answer is yes. In fact, many people very satisfied with their car audio system after installing marine speakers on their cars.

The biggest difference between a marine speaker and a car speaker lies in the protection against the harsh environment.

Since marine speakers built to survive the marine environment, it can handle moisture, dust, water exposure, and corrosion.

I would say that installing a marine speaker in your car will be an upgrade. Especially when we talk about the volume. Since marine speakers designed for ocean use, you will hear a loud volume when using it in a car.

Not to mention, its built-in protection features make it more durable compare to the regular car audio system.

However, there are a few things you to know before using a marine speaker for your car. First, you need to check their compatibility.

Try to find a marine speaker that suitable for car temperature. Other than that, since the component may vary, be sure to check your car’s compatibility level with the marine speaker.

After checking the compatibility, the next thing you need to pay attention to is the size of the speaker. Fortunately, marine speakers come in many different sizes.

So you need to find the one that can fit in your car. Also, remember that a car has far less space than a boat.

04. Which marine speakers are the best?

An excellent marine speaker must fulfill several factors. The most obvious one is to have a reliable waterproof feature. But other than that, sensitivity and power handling also play a critical role.

Speaker sensitivity will result in how loud the music will play out on the ocean. As for power, it determines how clear and free of distortion the sound will be.

05. How to install marine speakers?

Basically, it’s not hard to install a marine speaker on your boat. But there are some useful tips to achieve optimum sound quality and avoid short-lived speakers.

After buying a marine speaker, you need to prepare some tools and supplies. Here are some basic guidelines you can follow

06. Do I need a marine speaker?

If you own a boat and you like to enjoy your favorite music serenade your ocean venture, then you definitely need a marine speaker.

Some people think of using a car speaker on their boat instead of a marine speaker. Though it’s possible to do that, the speaker may not last long since it’s not built to handle harsh elements.

07. What is the difference between a marine speaker and a car speaker?

The major difference between marine speakers and car speaker is their ability to survive the tough environment. The marine speaker specifically built to endure the harsh marine condition.

They will handle heavy moisture, salty air, hot sun, and other harsh elements. They’re also made to produce a clear and loud sound that can resonate throughout the open water environment.

08. What are the loudest marine speakers?

Some popular brands in the market produce top-notch quality, marine speakers. We’ve carefully selected ten of the loudest marine speaker and write the review above.

So you can choose which one you think can suit your sailing trip best. Remember that the higher the sensitivity rating, the louder your speaker will sound.

09. How durable is a marine speaker?

Since marine speakers build with heavy-duty components, they aren’t going to wear out so quickly. The woofers are usually made of polypropylene known for its resistance against aggressive chemicals, including salt.

So if you buy a high-quality marine speaker, you can ensure that it will accompany many of your water escapades.

Marine Speaker basic installation guideline:

  1. Choose where you want to install your speaker. While choosing the spot, make sure the speakers are facing the ears of the listener. Otherwise, you may not get an optimum sound result.
  2. Drill new holes for the speaker. To cut the new hole, you can start by making a template of the hole. This step is only necessary when you’re installing a new marine speaker. If you are replacing an old speaker to a new one with the same type, then you can skip this step.
  3. Choose the ideal wire type for the speaker. Then you can begin to connect the speakers. After that, connect each speaker to the mounting spot and stereo unit wire one by one. It’s better not to use aluminum or steel speaker wires to avoid corrosion.
  4. The last step is mounting the marine speaker. First, you need to make sure the entire connected device is working. After you’ve tested all the wired connection, you can begin mounting the marine speaker into its permanent location.

For a smooth installation process, make sure you already have the tools to do the work. You can find a complete list of the tools and supplies on this page, along with some useful tips.


If you’re serious about taking your ocean venture to the next pleasurable level, then you seriously need a loud and reliable marine speaker.

Remember that when you choose a marine speaker, there are some critical factors you must take into consideration.

Other than the waterproof feature, you also need to pay attention to the sensitivity, power handling, and frequency response. Just read the reviews we provide earlier carefully.
